File formats

Notes

Detections are stored as a comma-separated values file, i.e. a text file that uses a comma to separate values. Each line corresponds to one detection. There is no header.

Time fields use the Unix time format with millisecond precision.

bCode detector

Each line describes one raw bCode detection and consists of the following fields:

1. time of detection
2. top-left fixed pattern, x-coordinate
3. top-left fixed pattern, y-coordinate
4. top-right fixed pattern, x-coordinate
5. top-right fixed pattern, y-coordinate
6. bottom-left fixed pattern, x-coordinate
7. bottom-left fixed pattern, y-coordinate
8. ID of individual
9. a mysterious number

Raw bCode detections can be converted to a more useful format.

Converter

Each line describes one human-readable bCode detection and consists of the following fields:

1. time of detection
2. x-coordinate
3. y-coordinate
4. orientation vector, x-component
5. orientation vector, y-component
6. ID of individual

Movement detector

Each line describes one movement and consists of the following fields:

1. time of detection
2. ID of individual
3. distance moved in mm
4. rotation around bCode center in radians

Trophallaxis detector

Each line describes one trophallaxis detection and consists of the following fields:

1. time of detection
2. ID of individual 1
3. ID of individual 2
4. probability that the individuals exchange liquid
5. probability that individual 1 donates

Flight activity detector

Each line describes one entrance event and consists of the following fields:

1. begin time
2. end time
3. ID of individual
4. type of event
